manhattan SC上关于gerunds修饰语的一个 例子牛牛们帮忙解惑下

besoru

Suspect:I like Mike SWIMMING.(= I like Mike only as he swims, not as he runs?  OR   I like for him to be swimming rather than lifting weights?)
Right    :I like Mike's SWIMMING.(= I like his swimming itself.)
Right    : Mike SWIMMING is a sight to behold.( Mike himself can be the sight.)
Right    : Mike's SWIMMING is a sight to behold.(The swimming can be the sight.)
我的主要疑问在为什么第一句Mike SWIMMING 存在歧义，而第三句却是正确的呢？难道第三句不存在歧义吗？
麻烦牛牛们解答下，不甚感激！

Right    : Mike SWIMMING is a sight to behold.( Mike himself can be the sight.) 这句话我知道SWIMMING是修饰MIKE。那这句话翻译成中文应该怎么理解. 这个SWIMMING放这里好碍眼啊，怎么都理解不了

我不是NN，不过刚刚想了一下。觉得是这样。前面那个like 那个句子歧义是因为，like,导致了swimming的修饰不仅仅在mike了，不仅仅是做形容词的位置，可能是like sb doing sth? 而第三句子swimming就是作为形容词修饰MIKE，所以不会有歧义~第三句的主语是mike.正在游泳的MIKE
